Embodiment
Hereinafter with reference to relevant drawings, the embodiment according to low-and high-frequency distributing antenna structure of the present utility model is described, to be convenient to understand for making, the similar elements in following embodiment is to illustrate with identical symbology.
See also Fig. 1, be the first schematic diagram of low-and high-frequency distributing antenna structure of the present utility model, this design is applicable to portable electronic devices.In figure, the first antenna 1 comprises the first antenna body 11 and first node 12; The second antenna 2 comprises the second antenna body 12 and Section Point 22; The first antenna 1 and the second antenna 2 and the set one side that is placed in substrate 3 of other elements are called component side, and the other side of substrate 3 is commonly used to configure the circuit that connects use.When signal was exported, the effect of node was to be connected to send by circuit the output signal that tendency to develop is sent, and introduced antenna body and vibrate, and became electromagnetic wave and sent to the space; When signal was inputted, electromagnetic wave became electric current in antenna body resonance, then is sent to other circuit by node.
The frequency range of the first antenna 1 is the part frequency range of containing portable electronic devices, is called the first frequency range; The frequency range of the second antenna 2 is another part frequency range of containing portable electronic devices, is called the second frequency range.For the frequency range of reaching full blast uses and avoids frequency range to overlap, if the first frequency range is high frequency and the second frequency range is low frequency, the low-limit frequency of the first frequency range can equal the highest frequency of the second frequency range; Conversely, if the first frequency range is low frequency and the second frequency range is high frequency, the highest frequency of the first frequency range can equal the low-limit frequency of the second frequency range.In addition, the use frequency range that portable electronic devices uses will be comprised of the first frequency range and the second frequency range, and in other words, the summation of this two frequency range must equal the use frequency range that portable electronic devices uses.
See also Fig. 2, it is the second schematic diagram of low-and high-frequency distributing antenna structure of the present utility model.Due to the first antenna 1 and the second antenna 2 independent of one another, and its structure more simply to reach area less, so the designer can freely select to carry out antenna configuration for convenience of favourable position.This figure shows that the antenna configuration of Fig. 1 can move to upper other comparatively favourable positions of component side, and then increases the elasticity of system.
See also Fig. 3, it is the system concept figure of low-and high-frequency distributing antenna structure of the present utility model.In figure, be provided with a Signal Matching circuit 4 in the component side of substrate 3, formed by the first resistance 41, the second resistance 42, the 3rd resistance 43 and inductance 44.Signal Matching circuit 4 couples with first node 12, and is used for the import and export signal of the first antenna 1 is mated.
Moreover, also have a substrate signal import and export end points 5 and be arranged on the component side of substrate 3, and couple the second antenna 2 and Signal Matching circuit 4, and substrate signal import and export end points 5 is the public same end points that the first antenna 1 and the second antenna 2 carry out the signal import and export.
The design of match circuit is to make the import and export signal to obtain the transmission of maximum power, therefore needs to coordinate the frequency of the defeated signal of tendency to develop to be designed.Therefore the Signal Matching circuit 4 in Fig. 3 can be the design that coordinates high-frequency signal, also can coordinate the design of low frequency signal, but the match circuit of height frequency signal, and its component kind and numerical value may be different.For example, Signal Matching circuit 4 in Fig. 3 is made of the first resistance 41, the second resistance 42, the 3rd resistance 43 and inductance 44, when low frequency signal is sent in Signal Matching circuit 4, can be sent to ground connection and disappear by inductance 44, therefore be the match circuit to high-frequency signal, and the second antenna 2 is high frequency antenna.When high-frequency signal was sent in the portable electronic devices tendency to develop, signal was sent to substrate signal import and export end points 5 by circuit, then entering signal match circuit 4, and then delivered to the second antenna 2 and transmit; When receiving high-frequency signal, carry out with reverse path, the signal that the second antenna 2 is collected, entering signal match circuit 4, then be sent to subsequent conditioning circuit by substrate signal import and export end points 5.The operation that transmits and receive low frequency signal is very similar, but exempts Signal Matching circuit 4, and when low frequency signal was sent in the portable electronic devices tendency to develop, signal was sent to Signal Matching circuit 4 by circuit, and then delivered to the first antenna 1 and transmit; When receiving low frequency signal, carry out with reverse path, the signal that the second antenna 2 is collected enters substrate signal import and export end points 5 and is sent to subsequent conditioning circuit.
Comprehensively above-mentioned, by low-and high-frequency distributing antenna structure of the present utility model, the simple and efficient rate double antenna so that the height frequency is distributed replaces complicated wideband single antenna commonly used, can effectively simplify the design of antenna and dwindle area, and improving simultaneously the antenna efficiency of high frequency and low frequency.In addition, this double antenna is independent of one another, and the integration of signal sees through Signal Matching circuit and substrate signal import and export end points, and the designer is less area or the position configuration antenna at edge comparatively on can free selectors face, and then the designer is provided larger elasticity.In addition, better simply antenna structure, hardware are easier to realization when producing, and yield is also higher, therefore are minimized cost, and are fit to a large amount of production.
The above is only illustrative, but not is restricted.Anyly do not break away from spirit of the present utility model and category, and to its equivalent modifications of carrying out or change, all should be contained in the claimed the scope of the claims of claims.
